実験手順

HBTU (284 mg, 0.75 mmol) was added to a solution of 1-methylcyclopropanecarboxylic acid (75 mg, 0.75 mmol), N,N-diisopropylethyl amine (194 mg, 1.50 mmol) and (3aS,7aS)-1-(1,4′-bipiperidin-4-yl)hexahydro-1H-benzo[d]imidazol-2(3H)-one (153.22 mg, 0.50 mmol) in DMA (10 mL) and stirred at room temperature for overnight. Concentrated in vacuo, diluted in dichloromethane (50 ml) and washed with sat. NaHCO3 (10 mL). The organic layer was dried over MgSO4, filtered and concentrated in vacuo. The crude product was purified by high pH Prep LCMS to give the titled compound (40 mg, 20.6%). 1H NMR (400 MHz, CHLOROFORM-D): δ ppm 0.51-0.59 (m, 2H) 0.86-0.94 (m, 2H) 1.30 (s, 3H) 1.33-1.45 (m, 6H) 1.68 (s, 1H) 1.74-1.84 (m, 7H) 1.96 (d, J=10.16 Hz, 1H) 2.21-2.32 (m, 3H) 2.48 (t, J=11.13 Hz, 1H) 2.76 (s, 1H) 2.92-3.03 (m, 4H) 3.71-3.81 (m, 1H) 4.49 (s, 3H). MS (M+1): 389.2
